Lonely? No. A loner? Perhaps.
There's just something about me, that prefers silence and solitude. It's not that I am anti-social, it's just that social gatherings, and social graces are just tiresome. I'm an introspective person, time to sit down and think about things in silence is just golden. It is refreshing.
Don't get me wrong though, when I'm fully charged and ready, I can easily navigate the ins and outs of being social and whatnot. When I feel it's worth the time and energy spent, it's doable. When I don't feel like it's worth it, I avoid it.
I am naturally just as passionate as I am logical, so in a way I need that time to think quietly. So that neither my logical side, nor my emotional side may rule me in excess. It is a fine balance and I enjoy thinking anyway.
